What is a CDN?
A content delivery network (CDN) refers to a geographically distributed group of servers which work together to provide fast delivery of Internet content.
The Domain Name System (DNS) turns domain names into IP addresses, which browsers use to load internet pages. Every device connected to the internet has its own IP address, which is used by other devices to locate the device. DNS servers make it possible for people to input normal words into their browsers, such as Fortinet.com, without having to keep track of the IP address for every website.

OpenVPN is a full-featured SSL VPN (virtual private network). It implements OSI layer 2 or 3 secure network extension using the SSL/TLS protocol. It is an open source software and distributed under the GNU GPL. A VPN allows you to connect securely to an insecure public network such as wifi network at anywhere. VPN is also required to access your corporate or enterprise or home server resources. You can bypass geo-blocked site and increase your privacy or safety online. This tutorial provides step-by-step instructions for configuring an OpenVPN “road warrior” server on Linux including ufw/iptables firewall configuration
WireGuard® is an extremely simple yet fast and modern VPN that utilizes state-of-the-art cryptography. It aims to be faster, simpler, leaner, and more useful than IPsec, while avoiding the massive headache. It intends to be considerably more performant than OpenVPN. WireGuard is designed as a general purpose VPN for running on embedded interfaces and super computers alike, fit for many different circumstances. Initially released for the Linux kernel, it is now cross-platform (Windows, macOS, BSD, iOS, Android) and widely deployable. It is currently under heavy development, but already it might be regarded as the most secure, easiest to use, and simplest VPN solution in the industry.
A Reverse Proxy is a web server that can put in front of another web server or a web service. It can encrypt outgoing traffic, act as a load balancer, redirect traffic, and offer protection. Nginx web server can be used as a proxy server in front of traditional servers, but sometimes setting it up can be tedious and cause issues if not done properly.
In this article we will discuss how to check the performance of a disk or storage array in Linux. IOPS (input/output operations per second) is the number of input-output operations a data storage system performs per second (it may be a single disk, a RAID array or a LUN in an external storage device). In general, IOPS refers to the number of blocks that can be read from or written to a media.
ZStack is open source IaaS (infrastructure as a service) software designed to automate datacenters and manage resources of compute, storage and networking through APIs. It is designed to tackle obstacles which prevent enterprises from adopting a private cloud in architectural design. Simplicity, stability, scalability, and extensibility are the main concerns in ZStack’s architectural design, which were taken into consideration from the very beginning.
